Be it known that we, Lnwis i l. llnivsim and THoMAs Roy lK-osn citizens of the United States, residing, respectively, at Los Angeles, in the county of La Angeles, and State of California, and at Calexico in the county of Imperial and State of California, have invented a new and useful Transmitting Mechanism, of which the following is a specification.

This invention relates to devices for transmitting the rotating movement of a shaft to the movements of pistons.

One of the objects of this invention is to provide a good power and motion trans initting means between a shaft and a piston.

Another object is to eliminate connecting rods between rotating shafts and reciprocat-- ing pistons.

between such rotating shafts and reciprocat ing pistons.

Another object is to provide a surer means for interconnecting rotating shafts and re ciprocating pistons.

Other means will appear from the following description and appended claims as well as from the accompanying drawing, in. which- 1 is a longitudinal 1n idscctional view of the device.

tion to the surface of the cam 4. his construction makes it possible that the pistons can be operated .vithout the usual. pivoted connectlng rods, the projecting or extension ends 8 being rigidly secured to or formed a part of the pistons, as will easily be understood.

The cam 4 of the device causes naturally the movement of the several pistons in one direction while the ring 10 causes the same pistons to move in the opposite direction.

It will furthermore easily be understood that, either, the shaft 01 the cylinders and therewith the pistons can he made the rotating part of the device. Clhis is to say that, if the shaft is to rot-etc, the housing (the cylinders 5, and therewith the pis ons, to a certain extent) will form the stationary part of the device; while, if the shaft is made to be stationary in some manner, the housing 5 can be rotated around the shaft, to give the same results.

This device can naturally be used in connection with pumps, and various lrinds of motors, as steam engines, explosive motors, and other similar devices.

Having thus described our invention, we claim:

1. In a transmission mechanism. plurality of cylinders and pistons slidably mounted. therein, prolongations or projecting ends on the pistons, anti-friction means mounted in said prolongations, a shaft, an endless rolling surface eccentric to said shaft. with which said means have anti-frictional contact and a free, independent and detachable ring mounted on said means concentric to said endless rolling; surface and having a free anti-frictional Contact with said means. In a transmission mechanism. plura ity of cylinde s and pistons slidably mount ed therein. prolongations or projecting ends on the pistons, and rollers inunted in tile ends thereof, a cam with which said rollers have rolling contact, and a free, independent and detachable ring mounted on said rollers concentrically with said cam, and having a free rolling contact with said rollers.
